Description
Active High Output. This pin is asserted when there has been no SPI activity on the interface pins for a
predetermined time. See the Device Features section for more information.
Active Low Output. This pin is asserted low when an open circuit in current mode is detected, a short circuit in
voltage mode is detected, a PEC error is detected, or an overtemperature is detected (see the Device Features
section). Open-drain output.
Hardware Reset. Active Low Input.
Positive Analog Supply. The voltage range is from 10.8 V to 33 V.
No Connect. Do not connect to this pin.
HART Input Connection for DAC Channel A. For more information, see the HART section. If unused, leave as an
open circuit.
Optional Connection for External Pass Transistor. Leave unconnected when using the dc-to-dc converter. See
the External PMOS Mode section for more information.
DC-to-DC Compensation Capacitor. Connect a 10 nF capacitor from this pin to ground. Used to regulate the
feedback loop of the Channel A dc-to-dc converter. Alternatively, if using an external compensation resistor,
place a resistor in series with a capacitor to ground from this pin (see the DC-to-DC Converter Compensation
Capacitors and the AICC Supply Requirements—Slewing sections in the Device Features section formore
information).
Supply for Channel A Current Output Stage (see Figure 50). To use the dc-to-dc feature of the device, connect as
shown in Figure 57.
Current Output Pin for DAC Channel A.
Ground Reference Point for Analog Circuitry. This must be connected to 0 V.
HART Input Connection for DAC Channel B. For more information, see the HART section. If unused, leave as an
open circuit.
Optional Connection for External Pass Transistor. Leave unconnected when using the dc-to-dc converter. See
the External PMOS Mode section for more information.
DC-to-DC Compensation Capacitor. Connect a 10 nF capacitor from this pin to ground. Used to regulate the
feedback loop of the Channel B dc-to-dc converter. Alternatively, if using an external compensation resistor,
